BBC News: Individuals who claim affiliation with the hacktivist group Anonymous have released their own operating system (OS). Already, more than 26,000 people have downloaded the OS from Sourceforge. Based on the Ubuntu distribution of the open source Linux OS, the software comes chock full of hacking tools.

However, experts caution users to be wary of the OS. One "official" Twitter account for Anonymous claims the download is full of viruses. "Folks would be wise to be very cautious," added Graham Cluley of security firm Sophos.
